Broadcast sheet mysteries

There were multiple printers scattered all over the plant, when the broadcast sheets were printed, it was truly a 'broadcast' but on paper.

The front seat assembly area had one printer & the rear seat assembly area had its own printer.

Those lines in your copy look like perforations from the thin steel listing wires, did you find it literally woven into the seat?

If so, the printer at one of the stations mentioned above may have been out of commission, so they may have had to obtain a copy from the closest station with a working printer.

We may never know for sure though.......
